I am not an expert in CAN bus however what I can say is that your transfer rate is 1Mb/s. Now depending on the number of bits you have in the signal then your baud rate would be 1000000/x (where x is the number of bits in signal). So you would need to know how many bits there are in your signal since these vary in the CAN bus.

Let me know if you require any further assistance or if this didn't answer your question.
